huber loss deep learning

What Is a Loss Function and Loss? Loss Functions and Reported Model PerformanceWe will focus on the theory behind loss functions.For help choosing and implementing different loss functions, see … This tutorial covers usage of H2O from R. A python version of this tutorial will be available as well in a separate document. So, you'll need some kind of … The sign of the actual output data point and the predicted output would be same.

I present my arguments on my blog here: Someone has linked to this thread from another place on reddit: [r/reinforcementlearning] [D] On using Huber loss in (Deep) Q-learning • r/MachineLearning, If you follow any of the above links, please respect the rules of reddit and don't vote in the other threads. The robustness-yielding properties of such loss functions have also been observed in a variety of deep-learning applications (Barron, 2019; Belagiannis et al., 2015; Jiang et al., 2018; Wang et al., 2016). Now I’m wondering what the relation between the huber_alpha and the delta is. 이번 글에서는 딥러닝 모델의 손실함수에 대해 살펴보도록 하겠습니다. This tutorial is divided into seven parts; they are: 1. I argue that using Huber loss in Q-learning is fundamentally incorrect. L2 Loss function will try to adjust the model according to these outlier values. One more reason why Huber loss (or other robust losses) might not be ideal for deep learners: when you are willing to overfit, you are less prone to outliers. A great tutorial about Deep Learning is given by Quoc Le here and here. I'm a bot, bleep, bloop. If it is 'sum_along_second_axis', loss values are summed up along the second axis (i.e. berhu Loss. <> It is less sensitive to outliers in data than the squared error loss. stream What Loss Function to Use? This is an implementation of paper Playing Atari with Deep Reinforcement Learning along with Dueling Network, Prioritized Replay and Double Q Network. This function is often used in computer vision for protecting against outliers. If you really want the expected value and your observed rewards are not corrupted, then L2 loss is the best choice. In this article, initially, we understood how loss functions work and then, we went on to explore a comprehensive list of loss functions also we have seen the very recent — advanced loss functions. The Pseudo-Huber loss function ensures that derivatives are continuous for all degrees. L2 loss estimates E[R|S=s, A=a] (as it should for assuming and minimizing Gaussian residuals). The Hinge loss function was developed to correct the hyperplane of SVM algorithm in the task of classification. The learning algorithm is called Deep Q-learning. you erroneously receive unrealistically huge negative/positive rewards in your training environment, but not your testing environment). This is further compounded by your use of the pseudo-huber loss as an alternative to the actual huber loss. Deep Q-Learning As an agent takes actions and moves through an environment, it learns to map the observed state of the environment to an action. This loss penalizes the objects that are further away, rather than the closer objects. Thank you for the comment. L2 Loss is still preferred in most of the cases. Hinge. L2 Loss(Mean Squared Loss) is much more sensitive to outliers in the dataset than L1 loss.
